The invention relates to the technical field of automobile tires, and particularly discloses a rolling resistance reducing type pneumatic tire which comprises a tire body, a plurality of longitudinal pattern grooves for draining water are formed in the tread of the tire body, and a plurality of transverse patterns for enhancing road holding force are arranged on the two sides of each longitudinal pattern groove; the longitudinal pattern grooves are open type pattern grooves which are narrowed at the positions close to the bottoms; by designing a new longitudinal pattern groove structure, the top of the tire is of an open structure, drainage can be facilitated, and the wet and slippery performance of the tire is guaranteed; the bottom is narrowed, so that the rigidity of the tread is ensured, stones can be prevented from damaging the bottoms of pattern grooves of the tread, and the driving safety and the use performance of the tire are ensured; on the premise of ensuring the rigidity of the tire tread and the rolling resistance of the tire, good drainage performance and tire slippery performance are achieved, and the practicability is greatly enhanced.
本发明涉及汽车轮胎技术领域,具体公开了一种降低滚动阻力型充气轮胎,包括:轮胎本体,所述轮胎本体的胎面设置有若干条用于排水的纵向花纹沟,所述纵向花纹沟的两侧均设有若干条增强抓地力的横向花纹;所述纵向花纹沟是在靠近底部的位置收窄的开放式花纹沟;通过设计新的纵向花纹沟的结构,使其顶部呈现开放式结构,能够有利于排水,保证轮胎的湿滑性能;底部收窄,在保证胎面刚性的同时,能够避免石子破坏胎面的花纹沟底部,保证行驶安全性和轮胎的使用性能;在保证轮胎胎面刚性和轮胎滚阻的前提下,兼具良好的排水性和轮胎湿滑性能,实用性得到极大的强化。
